Trouble with that is it treats both 1, and '1' (and 1.0 and '1.0') as looking like numbers (albeit with strangely different values of true)

use Scalar::Util qw(looks_like_number);;

[0] Perl> print looks_like_number( $_ ) for 1, '1', 1.0, '1.0', '1o';;

But the OP wants to distinguish between 1 stored internally as an integer; and '1' stored internally as a string.

In the absence of evidence, opinion is indistinguishable from prejudice.
